Revisiting the function of the HSV-1 UL45 protein.
Recombinant viruses containing either glycoprotein B (gB) or glycoprotein K (gK) mutations that confer a syncytial phenotype, and with or without UL45 expression, were generated to revisit the role of 18K in mediating cell fusion and showed that UL45 expression was not required for either gB- or gK-driven syncytial pla...
